Synergistic Dual-Coating Layers with Uniformly Anchored Zn-Containing Nanoparticles Enabling Structural Robustness and High Conductivity for High-Performance SiO Anodes

Abstract
Microsized silicon monoxide (SiO) anodes have attracted considerable attention owing to their high theoretical specific capacity, but their low electronic conductivity and severe volume expansion during cycling hinder practical application. Herein, a synergistic dual-coating strategy is developed to construct a trilayer SiO@SiOx/C@ZC composite anode composed of a SiO core, a homogeneous SiOx/C composite interlayer, and a ZIF-8-derived carbon outer shell containing uniformly anchored Zn-containing inorganic nanoparticles. Ξ³-Mercaptopropyltrimethoxysilane (MPTMS) was first coated onto SiO, where thiol groups anchored ZIF-8 precursors through coordination with Zn2+. After high-temperature calcination, the MPTMS-derived homogeneous SiOx/C interlayer buffered volume expansion and improved structural stability, while the ZIF-8-derived carbon shell enhanced electronic conductivity and constructed a continuous carbon network. The Zn-containing inorganic nanoparticles embedded within the carbon shell further facilitated interfacial Li+ transport. SiO@SiOx/C@ZC retained 885.72 mAh gβˆ’1 after 1000 cycles at 1 A gβˆ’1 with 84.2% capacity retention and delivered 553 mAh gβˆ’1 at 10 A gβˆ’1. Chemical prelithiation was further employed to compensate for the initial irreversible lithium loss and improve lithium utilization, enabling the SiO@SiOx/C@ZC//NCM811 full cell to maintain 150 mAh gβˆ’1 after 200 cycles at 1 C and to retain 70.86% of its capacity at 6 C during rate testing. This work provides an efficient strategy for practical microsized SiO anodes.

Magnetic Functionalization of High- Q Mechanical Resonators with Co 3 Fe Nanopillars for Spin-Mechanical Coupling

Abstract
Coupling electronic spin degrees of freedom to the motion of micromechanical resonators could enable quantum-enhanced force sensing, the exploration of macroscopic non-Gaussian states, and information transduction for hybrid quantum systems. A promising route exploits Zeeman shifts of spin states induced by the displacement of resonators functionalized with magnetic nanostructures. However, established nanomagnet fabrication methods, such as thin-film patterning, are incompatible with the inherently fragile nature of microresonators. Here, we report the successful growth of soft-ferromagnetic Co3Fe pillars, with a 500 nm diameter and 2000 nm height, on 50 nm thick SiN trampoline membranes by focused electron beam induced deposition (FEBID). We show that this functionalization preserves mechanical quality factors up to 7 Γ— 106, confirming that the FEBID process is noninvasive to the resonator. Using nitrogen-vacancy scanning magnetometry, we probe the magnetic properties of a pillar in external fields up to 15 mT and observe a clear opening of its hysteresis loop, indicative of ferromagnetic behavior with a small but finite coercivity. At an NV-Co3Fe pillar apex distance of ∼300 nm we directly measure magnetic field gradients of 3 Γ— 104 T m–1.

Sialic Acid-Functionalized Iron-Based Metal–Organic Framework Nanoprobe for Tumor-Targeted Near-Infrared Fluorescence/Magnetic Resonance Imaging of Cervical Cancer

βœ‡ACS Applied Nano Materials advanceAccess
9 September 2026 at 01:00
Abstract
Accurate localization and delineation of cervical cancer lesions are essential for precise surgical planning. However, conventional magnetic resonance imaging (MRI) often provides insufficient molecular specificity for tumor delineation, whereas near-infrared fluorescence (NIRF) imaging is restricted by shallow tissue penetration. Herein, we developed a sialic acid (N-Acetylneuraminic acid, Neu5Ac)-functionalized nanoscale iron-based metal–organic framework (MOF) nanoprobe, NH2-MIL-101(Fe)/Neu5Ac/Cy7, for tumor-targeted NIRF/MR dual-modal imaging of cervical cancer. The nanoscale Fe-MOF framework provides intrinsic T2-weighted MR contrast and serves as a functional scaffold for PEG/Neu5Ac surface modification and Cy7 loading. In SiHa cells, the Neu5Ac-functionalized nanoprobe exhibited approximately 2.1-fold and 3.9-fold higher intracellular fluorescence than the non-Neu5Ac-modified counterpart at 8 and 12 h, respectively. Time-dependent in vivo NIRF imaging further identified 8 h postinjection as a suitable imaging time point. In SiHa tumor-bearing mice, NH2-MIL-101(Fe)/Neu5Ac/Cy7 showed enhanced tumor-associated accumulation compared with control probes, as evidenced by pronounced T2-weighted MR signal attenuation and a 4.36-fold higher ex vivo tumor fluorescence intensity than the non-Neu5Ac-modified counterpart. Collectively, this nanoscale dual-modal imaging platform combines MRI-based deep-tissue localization with NIRF imaging sensitivity, offering a promising strategy for cervical cancer lesion visualization and tumor-region delineation.

Nanostructured Zirconia-Based Aerogels for High-Temperature Thermal Insulation

βœ‡ACS Applied Nano Materials advanceAccess
7 September 2026 at 13:01
Abstract
Zirconia-based aerogels are lightweight, porous materials made up of interconnected zirconia nanoparticles, forming continuous three-dimensional nanoporous networks. Their high melting point, low density, high porosity, and low thermal conductivity make them promising candidates for high-temperature thermal insulation and protection in extreme environments such as spacecraft thermal protection systems, high-speed aircraft, and high-temperature industrial equipment. However, their nanoscale frameworks become unstable at high temperatures. Processes such as nanoparticle sintering, grain coarsening, and temperature-driven phase changes can cause pore collapse, structural damage, and a reduced level of insulation. This Review evaluates zirconia-based aerogels from a failure-mechanism-guided, application-focused perspective. It highlights recent progress in fabrication techniques, nanoscale structural control, and thermal insulation performance with a focus on strategies that enhance phase stability and preserve nanopores. The text reviews strategies like heteroelement doping, structural control, surface and interface modifications, core–shell architectures, and fiber reinforcement, focusing on their impact on sintering resistance, phase evolution, mechanical properties, and heat transfer. It highlights challenges and future opportunities for developing thermally stable zirconia-based aerogels for extreme-environment thermal protection.
